1 Claim.

This invention pertains to new and useful improvements in wrenchesparticularly for adjusting internal combustion engine valves and has forits primary object to provide, in a manner as hereinafter set forth, adevice of this character embodying unique means for gauging theclearance of said valves.

Another very important object of the invention is to provide a tool ofthe aforementioned character in the form of a double end wrench whereinthe gauges are adapted to be expeditiously used with the jaw on eitherend.

Other objects of the invention are to provide a wrench of the characterdescribed which will be comparatively simple in construction, strong,durable, highly emcient and reliable in use, compact, light in weightand which may be manufactured at low cost.

All the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a bottom plan view of a tool constructed in accordance withthe present invention.

Figure 2 is a view in side elevation of the device.

Figure 3 is a cross-sectional view, taken substantially on the line 33of Figure 2.

Figure 4 is an end elevational View.

Figure 5 is a view in horizontal section through the tool.

Figure 6 is a view in vertical longitudinal sec,- tion, showing the toolin use.

Figure '7 is a perspective view of the gauges and the operating meanstherefor.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises ametallic handle I of suitable length. Integral jaws 2 are provided onthe ends of the handle I. Formed in the handle I is a chamber 3 whichterminates at points in spaced relation to the jaws 2. It will beobserved that the chamber 3 is open at its sides. Formed in the upperand lower portions of the handle I are slots 4 which communicate withthe chamber 3. Longitudinal passages 5 establish communication betweenthe chamber 3 and the nut reeciving recesses or openings 6 of the jaws2.

Mounted for sliding and swinging movement in the chamber 3 is aplurality of feeler gauges i of various thicknesses. The gauges I arepivotally connected at one end by a rivet or pin 8 which projectsthrough the lower slot 4. Mounted on the lower end portion of the rivetor pin 8 is an operating handle 9 which terminates, at

one end, in a finger receiving loop In.

It is thought that the manner of using the tool will be readily apparentfrom consideration of the foregoing. Of course, the jaws 2 are appliedto the usual valve nuts for turning same. To check the clearance ofthezvalve being adjusted, the gauges I are swung laterally, as suggestedin Figure 1 of the drawings. The desired gauge is selected and swungback into the chamber 3. The gauge unit is then moved forwardly throughthe medium of the handle 9 for projecting the selected gauge through thepassage 5 into the recess 6 of the jaw 2 on this end of the wrench. Whenthe desired check has been made the selected gauge may be convenientlyretracted from the jaw recess 6. The construction and arrangement issuch that the gauges I may be conveniently swung for use on either endof the wrench. When the gauges I are not in use they are enclosed in andprotected by the handle I.

It is believed that the many advantages of a wrench constructed inaccordance with the present invention will be readily understood, andalthough a preferred embodiment of the tool is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:

A tool of the class described comprising an elongated handle, a jaw onone end of the handle, said handle having a longitudinally elongatedchamber therein communicating with the jaw, said handle further havinglongitudinal slots therein communicating with the chamber, a pinoperable in the slots, a plurality of feeler gauges journaled on the pinand slidable in the chamber, said chamber being open on opposite sidesior swinging the gauges laterally from the handle for making a selectionof said gauges, the gauges being adapted for selective projection intothe jaw, and an operating handle secured on one end of the pin andoperable on the first-named handle, the second-named handle including afinger loop on one end.
